SPECIFICATION forming part of Letters Patent No. 425,379, dated April 8,1890.

Application filed January 31, 1889. Serial No. 298,240. l, (No model.) v

To all whom it may concern:

Be it known that I, EDWIN D. HILTON, of Paterson, in the county ot'Passaic and State of New Jersey, have invented a new and usefulImprovement in Looms, of which the following is a specification,reference being had to the accompanying drawings.

A I will first describe the improvement fully in detail, and afterwardpoint out its novelty in claims.

Figure l is a front view of all the parts of' a loom necessary toillustrate the invention, the breast-beam and the front part of theframing beingtaken away to expose the parts behind them to view, and allthe moving parts not involved in the improvement being omitted. Fig. 2is a right-hand end view correspending with Fig. l. Fig. 3 is a backView of the same. Fig. 4 represents a verticalsection parallel with theside of the loom in the line a: :t of Figs. l and 3, viewed from theright of Fig. l and from the left of Fig. 3. Fig. 5 is a sectional viewtaken nearly on the line y /y of Figs. 1 and 3. Fig. 6 is a front Viewof the swivel-rack on a larger scale than the preceding figures. Fig.represents a transverse section taken on the line e' e of Fig. 6. Fig. 8is a front view of the gearing, by which what is called the skip or mockmovement of the swivel-shuttles and their operating mechanism isproduced. Fig. 9 is a front view of the devices for shifting parts ofthe shuttle-operating mechanism from each to the other of the positionsfor plain weaving and swivel weaving. Figs. l0 and ll are views of theouter sides of the two cams for operating the swivel-shuttles, and Fig.12 is a side view of one of the cams for depressing the swivel-shuttlerack. p

Similar letters of reference designate co1'- responding parts in theseveral figures.

A designates the framing of the loom; B, the main shaft; C, the lay; D,the reed; E E', the picker-sticks for the ily-shuttles, all of whichparts may be the same as in ordinary looms for plain weaving.

F designates a cam-shaft, which is represented as occupying the sameposition as the cam-shaft of an ordinary loom for plain weaving anddriven by gearing from the main shaft" B, as will be hereinafterdescribed.

This shaft carries cams i'. t" and It k for operating theswivel-shuttles, as will be hereinafter described; and its gears F F2,through which it derives motion from the main shaft, carry thelcam-rollers ff for operating the body or Viiy-shuttle treadles S S.These treadles may be connected with the pickersticks in any well-knownor suitable manner. They are represented as connected by straps b b',and the picker-sticks are represented as connected with the rock-shaft Cof the lay by springs d cl, as isv common in iiy-shuttle looms. v

G designates a horizontal bar or plate which forms the main support forthe swivel-shuttles and parts of their operating mechanism, the said barand its appurtenances being commonly termed the swivel-rack. The saidbar is firmly secured to two rods G', which are fitted to slide up anddown in guides c, fixed upon the back of the lay. The upper part ofthese rods are curved in goose-neck form to pass over the reed and thelay cap, as shown in Figs. 2 and 4. To the back of this bar G is secureda slide G2, and tothe bottom of this slide are secured a series ofplates g, which constitute the raceways for the swivel-shuttles H.Pivoted to the said slide G2 are toothed pinions g', which engage withtoothed racks on the swivel-shuttles and also with a sliding toothedrack g2, by the reciprocating movement of which the said shuttles aredriven through the pinions g. This toothed rack g2 is coniined in properrelation to the rack-bar G and slide G2 by a coveringplate g3, in whichthere is a slot g4 through which protrudes an eye g5, with which isconnected cords g6 for driving the toothed rack g2, which cords passover a series of guidepulleys 97. g8 Q9 and connect with theswiveloperating treadles I l. The guide-pulleys g7 are attached to theslide g2, as will be hereinafter described. The guide-pulleys g8 gf9 areattached to the lay. The treadlesl I', being alternately depressed bytheir respective cams t i', pull the cords g" in one direction Vand inthe other alternately, and so produce a reciprocating longitudinalmovement oi' the rack g2, which, through the pinions, operate theswivel-shuttles in the usual manner. The swivel-operating treadles I Iare each TOO furnished with a roller 2, upon which its respective cam e'or c" operates. These cams are both of the saine form,as shown in Figs.10 and 1l, and'each has a circular hub upon which its respective rollermay bear when the cam is not intended to operate, and the treadles l l'are movedout of operative position. The hub 3 of the .cam e' is of acircumference corresponding with the shortest radius of the cam; but thehub 3 of the cam i is extended in the form of a disk of a circumferencecorresponding with its longest radius, as shown in Figs. l0 and 1l, sothat when the treadles are intended .tobe at rest, one elevated and theother depressed, as shown in Fig. 4, the roller of each rests on thecircular hub of its respective cam.

K K ldesignate the treadles upon which the cams-lc k hereinbeforementioned act to bring down the swivel-rack G, and the swivelshuttlesand their operating mechanism to theirI operative level in front of thereed. The rods G' G are connected with these treadles by rods glo. Whennot depressed by these treadles, the rack and the swivel-shuttles andtheir immediate appurtenances are raised to the position shown in Figs.l, 2, 3, and 4 by means of spiral springs c', which are coiled aroundthe rods G', between their lower guides c and the collars c2 upon thesaid rods. rllhe two cams 7c 7c' are alike, and as bothoperate togetherthey are practically a single cam, and therefore it is obvious that asingle cam of the-same form and a single treadle might be substitutedfor the two cams lo k' and two treadles` K K', the two rods G G being insuch case connected by ayoke cross-bar and the Y latter being connectedwith the single treadle.

The iiy-shuttle treadlesS S and the t-readlesy I- I and K K', foroperating the swivel-shuttles, are all pivoted upon a horizontal shaft J,which is supported in fixed bearings a on the back part of theloom-framing, and they are confined to t-he said shaft ina directionlengthwise thereof between collars j j thereon, so that they may allmove together with the said shaft when it is moved lengthwise, ashereinafter described, for the purpose of changing the relation betweenthe said treadles and their respective cams for changing the opera.-tion` from plain weaving to swivel-weaving without moving the cani-shaftlengthwise. The treadle-shaft J has a constant rotary motion, which isentirely independent of the treadles, at a speed corresponding with thatof the cam-shaft F, the said rotary motion being` derived from thecam-shaft through gears F* and J ik, one fast on each shaft.l One of thegears F* J it (the gear F* on the cam-shaftV in the exam-plerepresented) is made wide enoughv to allow the two to remain gearnotwithstanding the lengthwise movement of the shaft Ji".

The cam-shaft F has fast upon it at one end a gear .F and at the otherend a larger gear F?, and each of these gears with` one of the always inf and F2 are proportioned to give the cam-shaft y 8o one'revolution forevery four revolutions of the main shaft. The'faster motion is Lto begiven to the cam-shaft when plainfweaving only is performed, and theslower motion when swivel weaving also is to be performed.

ln this way the same loom may be used to- `perform plain weaving as fastas an ordinary loom for that purpose, or may be used for swivel-weavingwith the -desirably slower motion of its other parts, relatively to thatof the main shaft and lay for that kind of weaving.

The lengthwise movement of the treadleshaft J, hereinbefore described,pose of effecting the changes of the treadles to the ca ms for plainweaving and swivel-weaving is effected by means of a double cam L (seeFigs. 3 and 5,) on thesaid shaft J and a reversible engaging device forengaging with 'the said cam. The said reversible engaging device isrepresented as consisting of an inverted -T- shaped tumbler M, (seeFigs. 3, 4, and 9,) which is ypivoted byA a pivot Z to a stationarybracket Z, securedto the loom-framing, and from which are suspended twofingers m m', which are guided in guides in the bracket Z, and either ofwhich is capable of 'being engaged with the said cam while the other isdisengaged therefrom. This double cam has two sets of reversely-arrangedgrooves n o p and n 0 p', each set consisting of a groove n or n whichruns uninterruptedly directly around the cylinder in a planeperpendicular to the aXis thereof, a groove o oro' parallel with itsrespective grooven or n', and an oblique groove p or p', forming across-over communication between the grooves n 0 or n o.

The tumbler is to be operated bysuitable connections, as wires q q',(see Fig. 3,) with a pattern-producing mechanism-such asa Jaequardmachine-so as to bring either the finger m or that m into engagementwith its respective set of grooves n op or n' o p in the cam, the otherfinger being at the same time disengaged from the cam. When the shaft Jis in position for the treadlesI I'and K K to be in range with theirrespective cams e' i' 'and la lo', as ,shown in Figs. 3 and 5,the fingerm is in the uninterruptedv groove 'n' and the `finger m entirely out ofrange of the cam, as

shown in-Fig. 3, and no longitudinal movement of the treadle-shaft Jtakes place; but

when it is desired to throw the swivel-shuttles fOr 'the .pint--4relation of similar, b ut` IOO IIO

ISO

out of operation the wire q" is pulled up, and4 the tumbler M is thrownover to the left to take the finger an' out of the groove In and bringthe finger 'm into the groove o. The continued rotation of thetreadle-shaft .I then brings the oblique cross-over groove p to thefinger m and causes the cam to move laterally on the said finger, and soto move the treadleshaft .I lengthwise to the left of the position shownin Figs. 3 and 5, and thus take the the continued revolution of thetreadle-shaft produces it-s movement to the right by an operationprecisely the reverse of that just described with reference to itsmovement to the left, and the t-readles I I and K K are again broughtwithin range of their cams it" and k it. A spring s connects the tumblerM above itspivot Z with the bracket Z in such manner as to hold it ineither of the two positions by which it may be thrown over by the wiresq q.

The longitudinal movement of t-he treadleshaft .I besides taking theswivel-treadles II and K II into and out of range with their respectivecams, also takes the iiy-shuttle treadles S S into and out of range withtwo sets of cam-rollers j' and f carriedV by the gears F and F2, the oneset for operating the said trendles while plain weaving only is beingperformed, during which operation the fly-shuttles require to malte fourpicks for every revolution of the cam-shaft, and the other set foroperating the said treadles Iwhen the operations of plain and swivelweaving are being performed, during which operations the iiy-shuttlesrequire to make but two picks for every revolution of the cani-shaft,the operations of the ily-shuttles and the swivelshuttles in the lattercase alternating with each other. The arrangement of the camrollers f ffor this purpose maybe understood by reference to Figs. 2,3, and 5. Onone side ot' the loom there are two cam-rollers ff', arrangeddiametrically opposite each other, as shown in Fig. 2. The roller f onthe right side of the loom (see Fig. l) is set out so far from the gearF2, which carries it, that when the treadles are in position forswivel-weaving, as shown in Fig4 l, the said roller will in itsrevolution pass outside of the treadle S on that side of the loomwithout operating the said treadle, yet the said roller will operate onthe said treadlc when the treadle is moved outward bythe longitudinalmovement of the shaft .I to the position for plain weaving. The roller fon the same side of the loom is long enough in the direction of its axisto operate on the treadle S in' either of the positions of the latter,and hence it always operates. On the other side of the loom there arethree rollers f f f. This roller f stands out so far from the gear F',which carries it, that it will only operate on the treadle S when thetreadle-shaft .I and all its treadles are in position forswivel-weaving, as shown in Figs. l, 3, and 5. These two rollers f j",which are diametrically opposite each other, one before and the onebehind the roller f, on the same side, are so close to the gear F thatthey will both operate on the treadle S only when the shaft .l and allits treadles are in operation for plain weavinv.

In order to provide for what is known as the skip or mock motion of theswivelshuttles, which is necessary to cha-ngc the po sition widthwise ofthe warp of the figures to be produced by the said shuttles, the slideG2 is so secured, as shown in Figs. d and 7, to the rack-bar G by boltst, passing through `slots t in the said bar G, but secured firmly bynuts 2 to the slide G2, that the said slide and all its attached parts,including the raceways, the shuttles, the toothed rack g2, pinions g',and pulleys gl, may move a certain distance crosswise of the loom. Inorder to provide for effecting this movement, there is secured to theback of the slide'a shorthorizont-al toothed rack u, (see Fig. 7 whichgears with a pinion u', which turns freely on an upright stud u2,secured iixedly in or on the laycap D', and which gears with afacetoothed wheel n3, which is capable of turning freely on a stud n2,secured in a standard a5, which is erected firmly on the lay-cap D. Thisstan dard carries also another stud u, on which turns a toothed sectorai, which gears with a toothed sector as, which is secured to or integalwith the toothed wheel ai. By turning this sector ai in one direction orthe other on its pivotal stud n it will be made to turn the sector u2and the wheel n.3, and through the latter to turn the pinion n', and so,by the action of the latter on the rack u, to produce the movement ofthe slide G2, and the swivel-shuttles, their raceways, and pinions g inone direction or the other.

The movement of the sector '1i-7 for effecting the skip or mock movementabove described is to be produced by suitable connectionsas rods, wires,or cords c liffwith any suitable pattern mechanisnr-as, for instance, aJacquard machine. The said sector is held in either of the positions towhich it may be moved by the connections fo c by means of a spiralspring n2, which is connected with it above its pivotal stud a6, andalso connected with the pivotal stud a4 of the wheel n3 and sector u8.

In orderthat the pinion u may always remain in gear with the toothedrack u, notwithstanding the rising and falling movement ofswivel-shuttles and their supporting and operating mechanism, the saidrack is made of a width equal to the said rising and falling movementadded to the width of the IOC IIO

pinion, as may be understood by reference to Fig. 7.v

ln order to take up the slack of the cord 96, or rather to avoid theslackn ess which would occur in the said cord owing to the mock mo-`tion unless some means of preventing it were provided, the guide-pulleysgT for the said cord are pivoted to arms t3, which are pivoted to thesliding plate or bar G2. rlhe bolts t, hereinbefore described, arerepresented made to serve as the pivotsl for the said arms. The saidarms are drawn by the said cords against fixed stops t1, provided on thebar or plate G on the outer sides of said arms, and as the slide G2moves in onedirection or the other the arm t3', which is in advance inthe direction in which the bar moves, is pressed against its stop t4 andso caused `to be moved toward va vertical position and so take up itscord, while the other arm is allowed to fall away from the verticalposition, and thereby let out it-s cord. This action may be betterunderstood by reference to Fig. 6, in which the slide G and its attachedparts are supposed `to be in their extreme left-hand positions when theleft-hand cord g is taken up and the right-hand one let out.

What I claim as my invention, and desire to secure by Letters Patent, is
